Cal. Code Regs. tit. 23 § 3939.54
On December 8, 2016, the Regional Water Quality Control Board, Los Angeles Region (Los Angeles Water Board) adopted Resolution No. R16-008 to incorporate stakeholder-developed groundwater quality management measures for salts and nutrients in the Upper Santa Clara River Groundwater Basin of Los Angeles County. The State Water Resources Control Board approved the amendment under Resolution No. 2017-0028, on May 16, 2017.
Resolution No. R16-008 amends the Los Angeles Region's Basin Plan by incorporating stakeholder-developed groundwater quality management measures for salts and nutrients in the Upper Santa Clara River Groundwater Basin in Los Angeles County into Chapter 8 "Groundwater Quality Management -- Sustainability and Basin-specific Protection of Groundwater". The stakeholder-developed management strategies for salt and nutrients are designed to maintain water quality that is protective of beneficial uses, while increasing recycled water use and allowing for the sustainable use of groundwater. These strategies will be applied in conjunction with already existing water quality protection measures in the planning area (e.g. TMDLs).
